ARTHUR O. HUBBARD, OF MINNEAPOLIS, MINNESOTA; NELLIE H. HUBBARD, TRIX, OF SAID ARTHUR O. HUBBARD, DECEASED, ASSIGNOR T PUFFER-HUBBARD MANUFACTURING COMPANY, OF MINNEAPOLIS, MINNESOTA, A CORPORATION OF MINNESOTA.

Application led November 28, 1921.

To all whom t may concern. l Be it known that I, ARTHUR O. I-IUBBARD, a'citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Metal Clothes Wringers, of which the following is a specification.

The object of my invention is to simplify l0 and improve the metal wringer shown and described in my application for Letters Patent of the United States, Serial No. 383,442, filed May 22,1920 issued November 13, 1923, #1,473,769.

A further object is to provide a wringer of comparatively few parts which can be easily and quickly assembled.

The invention consists generally in various constructions and combinations, all as ,20 hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a side elevation of a. metal clothes winger embodying my invention,

Figure 2 is a vertical transverse sectional view of the same,

Figure 3 is a longitudinal sectional View showing the relative arrangement of the wriger rolls and bearings,

F ifrure 4 is an end View of the wringer,

Figure 5 is a sectional view on the line 5 5 of Figure 3.

In the drawings, the wringer frame is shown composed of forward and rear metall'ie sections having their abutting faces {itting snugly together and secured by bolts or other suitable means. These sections I .will designate -broadly by reference letters A and B. Specifically, each section comprises an arched middle portion 2 integral with end rails 3 and 3a -joined together across the front and. rear of the frame by integral webs 4. Integral strengthening and finishing ribs 5 are joined to the upper portion of the rails 3 on both sides and extend along curved lines to the upper edges of the webs 4 and there merge into horizontal lips 5a which form an upward extension of the webs 4 and have outwardly and downwardly inclined surfaces 6 in the front and rear of the wringer rolls.

METAL CLOTHES WRINGER.

Serial No. 518,360.

The rail 3 is provided with outwardly1 projecting lugs 7` on the front and rear sections and a bolt 8 passes through these lugs and through the upper portion of a housing 9 for securing the. wringer frame thereto. Mechanism is provided within this housing for operating the rolls, as will hereinafter appear. Boltsl() and 10a connect the forward and rear sections of the rails 3 and 3a for clamp-ing them securely together and bolts 11 and 12 pass through the arched top portions or sections A and B for clamping them together. Lugs 13 depend from the lower portion of the rail 3, a clamping bolt 14 passes through these lugs and a bolt 15 is loosely pivoted thereon at one end and adjustably connected at its opposite end with a bracket 16 on the lower portion of the housing 9, thus providing means for clamping the housing -and the wringer frame firmly together. Lugs 1,7 and 173L de pcnd fro-n1 the lower portions of the rails 3 and 3a and bolts 18 pass through these lugs and aid in clamping the lower portions of the wringer sections together. The lugs 13 and 1T are preferably connected by webs 13a.

The wringer frame sections are hollow, as indicated in Figure 3, and the rail 3 has an extension housing 19 thereon integral with the remaining portion of thc frame, preferably, and wider, as indicated in Figures 1 and 4, to provide room for the operation of the wringcr roll gears. A space 20 is provided within the housing 19 for these gears and integral ribs 21 formed on the innerl walls of the rail sections 3 separate this space from. chamber 22. a corresponding chamber 22a being provided at the other end of the wringer frame in the rail sec` tion 3a.

In the lower portion of these chambers 22 and 22a, blocks 23 of suitable material, such as wood, are seated, having bearings for a shaft 24 on the lower wringer roll 25. The upper wringer roll 26 has a shaftV 2T and blocks 28 are arranged in the chambers 22 and 22 to bear on the shaft 27 and slide vertically in the guideways `in said chambers 22 and 22a formed by the ribs 21 and the walls of the wringer rails. The shaft 24 has a squared extension 29 which projects through the wall of the wringer frame and is adapted for connection with a suitable source of power (not shown).

Upon the` shafts 24 and 27 driving gears are mounted, those on the shaft 27 meshing with the gears on the shaft 24 .to be driven thereby when the rolls are in their working relation.- A spring plate 31 is ar ranged to bear on the blocks 28 and a bar 32 is pivoted at one end on the bolt 11 and carries a screw 33 that is arranged to contact with the middle portion of the spring 31 and exert a downward pressure thereon. A lever 34 is pivoted on the bolt 12 and has a jaw 35 arranged to engage a lug 36 von the end of the bar 32 and is normally held in said engagement by-the tension of a spring 37. A lug 38 on the lower portion of the lever 34 engages a stop 39 and limits the upward movement of the lever 34 when it is released from engagement with the bar 32. Evidently, when this bar is in its horizontal locking position, pressure will be ap.- plied through the screw 33 to the spring 31 to lforce the rolls together and hold them with a yielding pressure, the degree of i which will depend upon the adjustment of tion, either forwardl the screw. When the lever 34 is tripped, the bar will immediately be released and the rolls allowed to separate. l

The lugs 17 and 17a support brackets 40 and said brackets are connected by a rod 41. A drip plate 42 has depending fianges 43 recessed at 44 to receive the rod 41 and slide thereon, the shoulders in the flanges 43 at the ends of the recess 44 limiting the sliding movement of the drip plate thereon. The ends of the drip plate are folded upwardly and downwardly, as indicated at 45, to present a rounded, smooth eii'ect, corresponding substantially to the surface of a roller, and ports 46 are provided in the'drip plate near these rounded portions, through which the drippings from the clothes may escape. Above the drip plate upwardly projecting flanges 47 are provided and these are preferab yvertical extensions-of the flanges 43, whic are preferably pressed from sheet metal seated against the underside of the drip plate 42 and secured thereto by suitable means, such` as rivets 48. Tle fianges 47 preferably have notches 49 near their middle portion and latches 50 are mounted in pairs on the front and rear of the sections A and B and are adapted to slip into the `notches 49 and lock the drip plate in its tilted posior backwardly, as indicated by full and tted lines in Figure 4.

in under the lower wringer roll, being separated by a gap 51 through which the water may flow from the rolls down upon the drip plate, being guided thereto by the curvature of the webs 4.

I claim as my invention:

1. A clothes wringer comprising two corresponding metallic members fitting one against the other and means for securing l them together, said members comprising end rails and integral arched portions between them, integral websv horizontally connecting the lower ends of said rails, and having inwardly and downwardly. curved portions,

integral ribs extending inwardly and downwardly from the upper portions of said rails and merging into the upper edges of said webs, and upper and lower wringer rolls mounted in said rails between said ribs and webs.

2. A clothes wringer comprising two corresponding metallic members tting one against the other and means for securing them together, said members including end rails and arched integral middle portions between them, integral webs connecting the opposite lower portions of said end rails and having inwardly and downwardly curved portions with a narrow longitudinal gap between them, and upper and lower wringer rolls mounted in said rails above said gap.

3. A clothes wringer comprising two corresponding metallic members fitting one againstthe other and means for securing them together, said members including end rails land arched integral middle portions between them, integral webs connecting the opposite lower portions of` said end rails and having inwardly and downwardly curved portions with alongitudinal gap between them, the upper edges of Asaid webs being fianged and having outwardly and downwardly inclined surfaces thereon, and upper and lower wringer rolls mounted in said rails above said webs.

In witness whereof, I have hereunto set my hand this 22d day of` November, 1921.

ARTHUR O. HUBBARD.
